For this question, you can Answer Yes if: Your facility has formally adopted and implemented the ZDHC Roadmap to Zero (or the Supplier to Zero) program on sustainable chemical management and its impact areas or other chemical management-related industry programs.
Note:
Adoption is the decision to use the ZDHC MRSL or other guidelines for your business, as evidenced by changes in the company’s internal and external policies and communication.
Implementation means steps are taken (beyond adoption) to put these decisions into action. Implementation could be, but is not limited to: training, change in purchasing/manufacturing practices to align with the program, or adopting and monitoring metrics to track compliance with the policy.
As such, based on the above guidance even Level 1 in supplier to Zero would be enough.
